The foot is connected to the leg by the ankle (talocrural) joint, which is an articulation between the tibia, fibula, and talus. The foot consists of 7 tarsal bones, 5 metatarsal bones, and 14 phalanges. Motion at the digits for abduction and adduction is defined by an imaginary line along the long axis of the second digit, unlike the hand in which the long axis runs along the third digit. Each digit, with the exception of the great toe, consists of three phalanges (proximal, middle, and distal); the great toe has two phalanges (proximal and distal). The articulations between the bones of the foot create multiple joints. The muscles that move these joints are divided into two groups, intrinsic and extrinsic foot muscles. The intrinsic muscles originate and attach in the foot, whereas the extrinsic muscles originate in the leg and insert in the foot, creating motion at multiple joints.
